All models require an adequate potable water
supply and a gravity drain. The recommendations
for tubing are:
•
Water supply to be
3
8
" OD.
•
Drain to be
3
4
" OD.
Note: When replacing a prior ice machine, do not
take a short cut and reuse the old inlet and drain
system. INSTALL A NEW SYSTEM.
Supply:
Water cooled models have TWO water supply
connections, a
3
8
" male flare for POTABLE water
AND an additional
3
8
" FPT condenser inlet
connection, both at the back of the cabinet.
Connect both to cold water w/adequate pressure.
Note: Using water supply tubing smaller than
3
8
"
will cause severe operational issues.
Water Filters:
The water filters must flow at least 2.7 GPM to the
potable water inlet or they will cause severe
operational issues. Check with the filter
manufacturer.
When replacing a prior ice machine, do NOT
assume that the water flow capacity of the filter will
be adequate.
All Drain Tubing Material must be RIGID.
Flexible tubing will eventually cause a
restricted drain.
Drain:
Water cooled models have TWO gravity drain
connections, a
3
4
" FPT fitting AND a ½ “ FPT
fitting. Use only RIGID TUBING. Flexible tubing
may be easily kinked or become cracked.
The reservoir drain must be vented at the back of
the cabinet. Use an 18" high vent. Do NOT vent
the condenser drain.
The ice storage bin will have a drain out the back
or base, depending upon the model.
The drain for the ice machine and the ice storage
bin must be SEPARATE or the ice machine’s drain
water may run into the bin and MELT THE ICE.
Insulation is recommended for the ice machine
reservoir and bin drains.
Follow all applicable codes
